Prime Series Diamond G4 SP

The Diamond Generation 4 marks the new chapter of Kosuzu Iwao’s signature series, celebrating the elegance and precision that defines the Diamond Range. Reflective of her confident and radiant presence on the oche, this latest model combines refined design with performance-driven engineering.

Crafted from 90% tungsten barrel design is the signature triple diamond ring structure, inspired by stacked jewellery rings. Each section features different groove depths and profiles, created through varied grip textures that help control and allow a non-slip grip, while helping the fingers settle naturally for a consistent release. Red line accents inspired by Kosuzu’s favourite colour, add a stunning and recognisable look. The straight barrel has a consistent diameter lengthwise, offering a simplistic and classic design. The three grip distinct zones offer versatility for different grip types. Three distinct grip zones offer versatility: softened shark cuts at the front support a smooth release, diamond pattern cuts in the centre provide clear grip reference, and mild shark cuts at the rear deliver dependable traction for a stable hold.

The barrel is finished with a black and red PVD coating, reflecting Kosuzu’s signature colour palette, giving the barrel a bold and modern look on stage.

Each set comes with red-printed K-Flex No.2 integrated flights and shafts, a one-piece system engineered for consistency and durability. Manufactured using advanced injection moulding techniques, K-Flex is engineered to absorb impact, reduce deflections, and prevent flight dropouts. Featuring a fixed 90-degree flight angle and a universal 2BA thread, the K-Flex system ensures smooth gameplay.

The dart is fitted with Swiss Nano points, designed to increase board grip through finely textured nano grooves. Integrated with Target’s patented Swiss Point System, the points can be quickly removed and replaced using the Swiss Point tool for easy customisation
